We welcome your feedback on this project. You are free to use the materials in any manner you wish. Interspersed in JetStream are "Learning Lessons" which can be used to enhance the educational experience. The information contained in JetStream is arranged by subject, beginning with global and large-scale weather patterns followed by lessons on air masses, wind patterns, cloud formations, thunderstorms, lightning, hail, damaging winds, tornados, tropical storms, cyclones, and flooding.

As the winds are diverted around the high areas, turbulence is created, and the disturbance in the flow continues downstream in the form of rows of vortices that alternate their direction of rotation. In this case, driving wind rushes past the tall peaks on the rugged Canary Islands. National Centers for Environmental Prediction.Preparedness and Mitigation: Individuals (You!).Preparedness and Mitigation: Communities.The Positive and Negative Side of Lightning.Tornado classesĪ tornado is an extremely violent weather event characterized by very strong winds and a tight vortex. The first half of the season is usually the most active, as this is when most weather conditions are most favorable for tornado formation. In recent years, however, there have been exceptions, so tornadoes can occur outside of the official season. This is when the risk for tornadoes is highest. Tornado season in the United States officially begins on June 1 and ends on November 30. The interactive map makes it easy to navigate. When does tornado season begin in the U.S.? See the latest United States RealVue weather satellite map, showing a realistic view of United States from space, as taken from weather satellites. Tornadoes can form very suddenly and are usually only a few minutes long. The greater the temperature difference between the cold and warm air, the stronger the vortex becomes. As the cold air rises, a vortex forms that continuously spins. The cold air is heavier than the warm air and pushes the warm air upward. Tornadoes form when cold and warm air mix. They are very dangerous and can cause severe damage. Tornadoes can occur over land or over water and usually range in width from a few hundred meters to a few kilometers. What is a tornado?Ī tornado is a rapidly spinning, powerful storm depression that rises from the lower levels of the atmosphere into the troposphere. The farther it is from the center of the storm, the more likely it is to form. And third, you should consider where the tornado is located. If it is horizontal, it is more likely to form. ![]() Second, you should consider the direction the tornado is pointing. The stronger the tornado, the more likely it is to form. When using tornado radar to predict where a tornado may occur, you should first consider the strength of the tornado. And if it’s pointing down, it’s moving northwest or southwest. If it is horizontal, it is moving either west or east. If it is pointing up to the right, it is moving southeast. If the tornado is pointing up to the left, it is moving northeast. The shape of the tornado on the radar gives information about its direction. The bigger and stronger the tornado is, the redder it appears on the tornado radar. The colors of the tornado radar tell you the strength of the tornado. Tornado tracker shows you the location of nearby tornadoes. When you use the tornado tracker to predict the weather, you should interpret it as if you were reading a map. If you use the tornado radar to predict the weather, you can also see where a tornado might occur. For example, you can see if there is a tornado nearby. When you look at the tornado tracker, you can learn some interesting things about the current weather. ![]() Tomorrow’s tornado probability in the U.S.A.
